Sjögrens syndrome

Sjögren’s syndrome is a highly heterogeneous and inflammatory rheumatological disease that has many overlapping features with other autoimmune diseases, specifically rheumatoid arthritis and systemic lupus erythematosus (Carsons SE et al. (2024). It is a chronic and systemic disorder, and presents symptoms such as dryness of the eyes, mouth, and other exocrine gland surfaces (Jonsson R et al. (2018)). The systemic nature of the disorder means organs such as the gastrointestinal tract, lungs, nervous system, and kidneys may be involved (Carsons SE et al. (2024)). It is a lymphoproliferative disease associated with high production of autoantibodies and is associated with an increased risk of B-cell lymphoma (Jonsson R et al. (2018)).

Differential Abundance Analysis Results

This section presents the results of the differential protein abundance analysis, visualized through a volcano plot and summarized in the accompanying table for all three comparisons: 1) disease vs. healthy samples, 2) disease vs. diseases from the same class, and 3) disease vs. all other diseases.
